    HINT:

    In case of performing resetting of the limit switch, do checking after repeating up and down of the glass with automatic operation.

    1. Confirmation of AUTO up operation:

      Confirm that the window will be fully close with AUTO up operation.

    2. Checking of the operation of the jam protection function:
      1. Move up the window with AUTO up operation and check that the window will go down when it touches the handle of the hammer stetted.
      2. Confirm that the window will then stop going down about 200 mm.

    HINT:

    In case of removing the glass, glass guide, regulator and etc. be sure to perform checking of the jam protection function.

    If the jam protection is not function properly, adjust power window motor reset switch and pulse switch.
